The upper disk is:proviriwl .ih sight :zpiwfnw snrmmuied hy de- .1". The. tubes 29 areadapted in him the iubvs 6 {LE the lower B th l (WIISUHBUOH :lhmo de-(IiRk M may be spaced 'Qrtiw Hjv with n m] 2 he base H. to allow :ntheights. This capacity of the measuring compartments defined by thetelescoped tubes 23-29 may be adjusted by shifting the upper disk 25along the shaft 12. The measuring compartments are spaced above andlocated slightly in ad vance of the can revolving fingers 19 so that. asillustrated at the extreme left of Fig. 2. a can 30 when in contact withone of the fingers 1 and within the runway 10?. will be pos tinneddirectly beneath one measuring compartment and will so remain throughoutthe orbital movement of the can. Thus material within the measuringcornpartments may pass directly into the cans, which are disposed incoaxial relation to the compartments.

lllounted above and held in contact with the upper disk 25 is a hopperplate 31 supported by brackets 32, which as illustrated in Fig. 2, arerigidly secured to the base 11. The hopper plate 31 as illustrated inFig. 8, is provided with an arcuate slot 33 of a. length approximatelyequal to the are defined by three of the measuring compart ments.Mounted upon the hopper plate 31 is an upstanding hopper casing 34 inwhich is placed the material with which the cans are to be filled. Inthe ordinary use of the machine the contents of the hopper 31-34 is dryalthough moist material may be used. In this connection it will also benoted that the number of measuring compartments and can revolvingfingers 19 may be varied without departing from the spirit of theinvention.

Supported by the brackets 32 and in contact with the lower disk 21 isavalve plate 35 which constitutes a closure for the lower ends of themeasuring compartments while the latter are positioned beneath and beingfilled by the hopper 31-34. The stationary valve plate 35 is providedwith a notch 36 which is positioned in the path of travel of themeasuring compartments and provides for a proper opening of the lowerextremities of the compartments as they pass beyond the stationary plate35. In this connection it is to be noted that the plates 31 and areprovided respectively with central arcuate notches 38 and 37 whichreceive for rotation the spiders which support the upper and lowerdisks. The plates 31 and 35 are adjustably mounted upon the brackets 32as shown at 100, thus allowing for the adjustment of the disks 21 and25.

A can receiving magazine 39 is formed by a plurality of spaced verticalrods one of which is attached to the base 11 and all of which areconnected to a ring 101 spaced from the base 11. Into this magazine thecans are inserted one upon the other with the openings therein at thetop. n order to feed the cans to the runway 10? defined between the drum14 and the rim 15, a vertical shaft 40 is provided and the same issupported in suitable bearings 41. The shaft 40 projects up through thebase 11. A circular plate 42 is rigidly secured to the shaft 40 andprojecting from the plate are wipers 43 which move transversely of themagazine 39 and advance the lowermost can along the arcuate portion 17of the rim .15 and into the path of the can revolving fingers 19. Thecan will thus be carried along through the runway 102 and be filled fromthe measuring compartment positioned directly thereabove and coaxialtherewith. The measuring compartments as they move from above the valveplate 35 will discharge into the cans and as the cans revolve about theshaft 12 as a center they will become filled and will be delivered fromthe runway 102. The cans are prevented from repeating the cycle by aguard 44 which extends above and below the path of movement of theactuating fingers 19 and terminates adjacent the peripheral edge of thedrum 14 so that as the can comes into forced contact with the guard, thecan will he moved tangentially of the drum, and will be advanced betweenthe guard 44 and the part 18 of the rim 15 along the delivery outlet104. The drive between the shafts l2 and 40 takes the form of a. chain45 and sprocket wheels 46.

A main driving shaft 47 is provided and the same is equipped at itsouter extremity with a belt wheel 48. Intel-posedv in the shaft 47 is aclutch 49 whereby the shaft may be intermittently or continuouslyrotated as desired. Theshaft 47 drives the vertical shaft 12 by means ofbeveled gears 50 and the shaft (12) in turn drives the can feeding shaft40. In order to control the machine further, a. clutch 51 is interposedin the shaft 40 and is operated by means of a lever 52, the constructionbeing such that the shaft 40 may be continuously or intermittentlyrotated with respect to the shaft 47.

Especial attention is directed to the fact that the plate 35 is providedwith the notch 36 in one edge. Further, it is to be noted that thediameter of each compartment is slightly greater than the distancebetween the base of the notch 36 and one end wall of the hopper 34.Owingto this feature, the discharge from the compartment into the canwill be initiatedby the weight of the material in the hopper, thusassuring a prompt filling of the can. Recalling the compartivelyinexpensive nature of the material handled by a device. of this type,noting that extreme accuracy is not called for, and that the cans,ordinarily, as sold are not filled to the extreme top, and observingthat any immcuracies resulting from the procedure above outlined may bepractically d are away with by elongating the compartments or shorteningthem, it will be obvious that no 'serious disadvantages fiow from i thefact that, .for a short period of time, a

small but unobstructed passage exists di' 'rectly from the hopper casing34: through the measuring compartment into the can.

Itlis to he observed, further, that the notch 36 is of approximatelysemicircular form, thereby to etfec't a complete openingot the bottom ofthe compartment when the compartment and the can are partially beneaththe plate 35, and consequently at an early stage in the cycles Havingthus described my inrent-iomnfhat I claim is In a can filling machine, asupporting I fran'ieembodying a base; a shaft journaled for rotation inthe frame; 'a plurality of measuring compartments carried by the sha; ashaft supported arm'indi'vidual to eaehcompartment and constitutingmeans for advancing cans along the base In vertica ahnement "with thecompartments; a hopper beneath which a part of the compartments registerat one time; and a frame supported plate forming a closure for the lowerends ofthe compartments which are l.eneath.the hopper, the plate havinga notch in one edge and the diameter of each compartmentlbeing slightlygreater than the distance between the base of the notch and one end wallof the hopper; whereby the dis charge front the compartment into the canwill be initiated by the weightlot' the'material into the hopper, thenotch being of approximately semi-circular form thereby to "etlect acomplete opening-of the bottom of the compartment when the compartment 7and the can are partially beneath the plate.

In testimony that I claim the foregoing as my own, I have hereto attixedmy signa- 4 ture in the presence of two witnesses.
